摘要:
［目的］城市轨道交通列车传统控制系统架构存在列车网络拓扑结构与布线复杂、子系统交互需增加延时等待、复杂控制过程容易出现配合不佳等问题。为提高牵引、制动响应速度，实现控制功能的融合，亟须开展列车关键系统的融合控制架构及方案研究。［方法］基于列车传统控制系统架构存在的问题，设计面向功能的列车融合控制系统方案，并对系统架构进行优化；基于TSN(时间敏感网络)的实时特性，设计TCMS(列车控制与管理系统)网络拓扑结构，阐明TSN在关键系统控制融合中发挥的重要作用；通过融合控制单元对列车牵引、制动、网络等关键子系统控制功能进行融合，实现关键系统控制功能高度集成，从而简化交互过程；在既有的牵引、制动控制单元基础上进行简化改进，设计功能趋于专一、面向执行的控制单元；结合理论分析，对列车融合控制系统进行实车验证。［结果及结论］列车关键系统控制功能的融合，可简化子系统间的交互，缩短控制响应时间，减少子系统的硬线连接，降低系统复杂度；列车子系统控制器仅面向执行，更为通用化。列车融合控制系统提高了关键系统的协同性，可实现快速响应的控制效果。
Abstracts:
［Objective］ The architecture of traditional urban rail transit train control system faces challenges such as complex train network topology and wiring, increased delays in subsystem interactions, and poor coordination in complex control processes. To improve the response speed of traction and braking and achieve integration of control functions, it is urgent to conduct a research on the integrated control architecture and scheme for key train systems. ［Method］ Based on the problems existing in the traditional train control system architecture, a function-oriented scheme for train integration control system scheme is designed, and the system architecture is optimized; in line with the real-time characteristics of TSN (time-sensitive network), the TCMS (train control and management system) network topology is designed, and the important role of TSN in the integration of key system control is explained; by integrating the control functions of key subsystems such as train traction, braking, and network through the integration control unit to, a high degree integration of key system control functions is achieved, thereby simplifying the interaction process; execution-oriented control units with specific functions are designed based on the simplified improvement of the existing traction and braking control units; combined with theoretical analysis, real-vehicle verification is conducted on the train integrated control system. ［Result & Conclusion］ The integration of key train system control functions can simplify the interaction between subsystems, shorten the control response time, reduce the hard-wired connection of subsystems, and reduce system complexity; the train subsystem controller is only designed for execution and more universal. The train integration control system improves the coordination of key systems, achieving a fast response control effect.Key wordsurban rail transit; train; multi-system integration control; timesensitive network
